Using the basic drip castle method we all loved as children, Harvard University lecturer Matthew Kaliner creates otherwordly sandcastles on the beaches of Boston's north shore. Motivated entirely by the sheer joy of playing on the beach, and making something out of what is readily available, Kaliner builds incredible structures that twist, jut, climb, and at times appear suspended in midair. “Although I enjoy watching the castles get swept away, I aim to make make my castles more resilient to waves by using sticks, anchored by elaborate braces I dig underground," he explained. "Watching the castle rising above the waves is a real treat—and that's always when they look best.”
